Abstract: The drone comprises altitude determination means (134), with an estimator (152) combining the measures of an ultrasound telemetry sensor (154) and of a barometric sensor (156) to deliver an absolute altitude value of the drone in a terrestrial system. The estimator comprises a predictive filter (152) incorporating a representation of a dynamic model of the drone making it possible to predict the altitude based on the motor commands (158) and to periodically readjust this prediction as a function of the signals delivered by the telemetry sensor (154) and the barometric sensor (156). Validation means analyze the reflected echoes and possibly modify the parameters of the estimator and/or allow or invalidate the signals of the telemetry sensor. The echo analysis also makes it possible to deduce the presence and the configuration of an obstacle within the operating range of the telemetry sensor, to apply if need be a suitable corrective action.

Robotic systems are used to robotically position a cutting element on an earth-boring tool. Systems for orienting a cutting element relative to a tool body include a power-driven device for moving a cutting element on or adjacent the tool body. Systems for positioning and orienting a cutting element on an earth-boring tool include such a power-driven device and a robot for carrying a cutting element. Systems for attaching a cutting element to an earth-boring tool include a robot carrying a torch for heating at least one of a cutting element, a tool body, and a bonding material.

Abstract: The apparatus comprises: a case (100), in particular a case that can be integrated into a motor vehicle dashboard; a front panel element (200), removably mounted on the case; and means for the reversible assembly and fixation of the front panel element to the case. Such means include: at a first end of the front panel element and of the case, a dismountable magnetic hinge comprising a first pair of magnetic elements (124, 224), arranged on the case and on the front panel element, respectively, opposite to each other and in mutual attraction; and at an opposed, second end of the front panel element and of the case, means for locking the front panel element to the case, comprising a lock (212) and a second pair of magnetic elements (126, 226), arranged on the case and on the front panel element, respectively, opposite to each other and in mutual repulsion.

Abstract: The drone (10) comprises an onboard video camera (14) picking up a sequence of images to be transmitted to a remote control. The user selects an exposure mode such as forward or sideways, panoramic or boom plane, tracking, defining a trajectory to be transmitted to the drone. Corresponding setpoint values are generated and applied to a processing subsystem controlling the motors of the drone. Once the drone is stabilized on the prescribed trajectory (38), the exposure by the video camera (14) is activated and the trajectory is stabilized by an open loop control avoiding the oscillations inherent in a servocontrol with feedback loop.

Abstract: The user inclines the apparatus (16) according to the pitch (32) and roll (34) axes to produce inclination signals (?I, ?I) which are transformed into corresponding command setpoints (?d, ?d) for the drone (10) in terms of attitude of the drone according to the pitch (22) and roll (24) axes of the drone. The drone and the apparatus each determine the orientation of their local reference frame (XlYlZl; XbYbZb) in relation to an absolute reference frame linked to the ground (XNEDYNEDZNED), to determine the relative angular orientation of the drone in relation to the apparatus. Then, the reference frame of the apparatus is realigned on the reference frame of the drone by a rotation that is a function of this relative angular orientation. The realigned values thus correspond to user commands referenced in the reference frame of the apparatus and no longer in that of the drone, which allows for more intuitive piloting when the user is watching the drone.

Abstract: A remote control unit carries control keys and possesses in its back face a battery housing with central and peripheral power supply contacts, and also with signal transmission contacts. An active support carries a portion in relief suitable for penetrating into the housing of the unit to take the place of the power supply battery. Two power supply terminals are connected to a power supply line and arranged so as to bear against the respective power supply contacts of the unit when the portion in relief is inserted and locked in the housing of the unit, with the same applying for signal transmission terminals that are arranged on the portion in relief in positions that correspond to the transmission contacts of the unit.

Abstract: The headset comprises two earpieces each having a transducer for playing back the sound of an audio signal and received in an acoustic cavity defined by a shell having an ear-surrounding cushion. The active noise control comprises, in parallel, a feedforward bandpass filter receiving the signal from an external microphone, a feedback bandpass filter receiving as input an error signal delivered by an internal microphone, and a stabilizer bandpass filter locally increasing the phase of the transfer function of the feedback filter in an instability zone, in particular a waterbed effect zone around 1 kHz. A summing circuit delivers a weighting linear combination of the signal delivered by these filters together with the audio signal to be played back. Control is non-adaptive, with the parameters of the filters being static.
